Synthetic sleeping bags use man-made insulation to trap air and keep you warm. Synthetic insulation is water-resistant, quick drying, easy to care for, and hypoallergenic. Because of its versatility, this type of insulation can be found in the widest variety of sleeping bags. Look for the EN, or European Norm, rating to get an idea of the lowest temperature at which a bag will keep you warm.

Mummy-shaped bags taper towards your feet to reduce volume and hold warmth closer to your body. These bags can feel restrictive to some. A semi-rectangular bag can offer more room to move.
